Be it known that 1, FREDERICK THOMAS,

a citizen ofzthe United States, .residingat Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented a new and usefulimprovem'ent in Arms for Creasing and like Machines, of which the following is a specification.

Objects of the present invention'are to ap ply steam to the edge of the cloth or part of the cloth that is to'be turned in creasing; to avoid staining? any part of the material that wouldshow even if water were accidentally applied to it along with the steam; to diminish the pressure required for creasing a fabric; and to provide convenience in ch nging the dies. Other objects of the invention will appear from the following description at the end of which the invention will be claimed after having been first described inconnection with the embodiment of it chosen fromother embodiments for the sake of illustration in the accompanying drawings forming which-- @Figure 1 is a top or plan view of an arm for creasing and like machines embodying or containing features of the invention.

Fig. 2 is a side view of the same, partly in section, and illustrating diagrammati cally features of the invention.

Fig. 3 is an end view, partly in section, looking toward the right in Fig. 2.

Fig. 4 is an end view or'inverted plan of the head of the arm.

Fig. 5 is a top or plan view with parts broken away of the die.

Fig. 6 is asectional view drawn to an en larged scale and taken on the line 6-6of Fig. 5, and

In the drawings 1 is'a head arranged at the end of the arm Q, and it is provided with a gasket receiving recess3 and with a projecting steam nozzle 4 communicating with the steam channel 5 provided in the arm. 6, generally, is a hollowrdie detachablyconnected with the head 1 as by means of screws and wing nuts 8. The die is provided with an opening 9 to its hollow interior 10, and this opening 9.:is adapted for the reception of the steam nozzle 4. The gasket 11.

arranged in the recess 3 around the nozzle at provides with the die a steam tight joint part hereof and in the parts of which are detachable. The die is provided with lateral steam discharge ori fices 12 arranged to discharge in the plane of the die and onto the edges a, Figs. 2 and 8, of the fabricwhich the the 18 adapted to turn up. As-shown the die consists of upiaeaeee per and lower plates 13 and 14 spaced apart I b saacers 15 and riveted to 'etherr "The spacers 15 are washers trung-on the rivets and disposed between plates 13 and 14, and so the plateswhile secured together] are) spaced apart, and this is one way of providing the orifices l2, and inthis case the orifices are bounded by the plates 13 and 14 and by the spacers 15. v The lower plate 14 extends beyond the edge of the upper plate 13. lVhere creasing is to be accomplished, for example, in Fig.'.5, at the bottom and sides of the'die, the spacers 15 assume the form, of rings and at the other edge they assume the form of a strip. Steam is sup; plied to the channel 5, andthis may be done by. pipe connections 16 which valve 17.

To change the die it is released from the head by the simple operation of taking off the wing nuts 8. and another die can be applied and secured by means of the wing nuts. The steam joint between thehead and die requires no attention when the dies are changed, When the die is applied to the fabric a,.the plate 14, in co-operation with the table Z) and elements 0 of a creas-- ing machine, operates to turn up the fabric as shown at a, and the valve 17 being opened, steam is discharged in the plane of.

applied to the, edges greatly facilitates their being creased, consequently comparatively include a little pressure is sufficient for properly op-.

erating the die.

It will be obvious'to those skilled in the art to which the invention relates that modifications may be made. in details of construction and arrangement without departingfrom the spirit of the invention which is not llmlted in respect to such matters or otherwise than as the prior art and the appended claims may require.

I claim:

1. 'An arm for creasing and like machines and a gaszet in said recess around said comprising in'combination ahead arranged at the end of the arm and having a gasket recess and a projecting steam nozzle com- Innnicatin with a steam channel provided in the head, a hollow die detachably connected with the head and having an openlngto its interior adapted for the reception of the nozzle and havin'gilateral steam' dis.-' charge orifices arranged to discharge in the plane of the die and ontotheedges of the fabric whichthe die is adaptedto turn'np,

nozzle.

QLAn arm for creasing and like machines comprising in combination a head having a steam channel through it, and a hollow die detachably attached to the head with its provided I with a die having an. 'impertorate face for contact with the t'abr 5' and having lateral steam discharge openings arranged to discharge in the plane of the die, substantially asdescribed; v

4. An; arm for creasing and like machines having a steam channel through it and having ahol'lowc die internally in communication with the channel and provided with edgewise discharging steam Or1tletsandwith an imperforate face. I i

' ri m'achin'e of the type described havranged todisiharge-in the' plane of the die and with an impert'orate face.

6. Acmachinebt' the type described having a die consisting ot'plates spaced'apart with steam dischargeopenings at their edges and connected together'and of which one is of larger area than the other and is imperforate in combination with means for supplying steam to the space between said plates; 7 I
